CEVA

1. Introduction and application

Chlorinated Ethylene Vinyl Acetate Copolymer (CEVA) is resin made by EVA through modification. It can be melted in organic solvent like toluene. Chlorinated EVA is widely applied in the production of superior printing ink, improving properties of adhesion and luster of printing ink. CEVA is a good binder for plastic products. It is applicable to high grade ink, additives for treatment of fibers, paint for biaxial tension polypropylene film and laminating agent for polyethylene / polypropylene films. It has been widely used in composite ink for high grade plastics in order for improving the ink’s adhesive strength, ink property, glossiness and the pigment’s dispersilbility, wettability and cold resistance, etc.
